Notes:
In order to investigate a viscoelastic-plastic nonlinear constitutive equation for polymer solids, combined tension and torsion tests were performed using polyethylene (PE) hollow cylinders. The experimental data were compared with the numerical results derived from a multiaxial constitutive equation developed from the uniaxial one proposed by Krempl. It is shown that the proposed theory fairly well describes the stress-strain curves of PE up to relatively high strain ranges not only in simple torsion, but also under combined tension-torsion, provided that the current strain is not below the maximum previous strain.
